Re PS : I have put my hand on an iPhone 4S this week-end, here are a few quick comments. Siri supports French, German, US and UK English. In French, voice recognition is pretty bad at the moment, and the command vocabulary is noticeably limited (it cannot answer "where" or "who" questions, manipulating agenda entries is painfully difficult). Considering that Engadget were quite impressed, I guess not all supported languages are equal. Hope this helps.
